C–H functionalization of electron-deficient heteroarenes using commercial unactivated alkyl halides through reductive quenching photoredoxcatalysis was developed. Mainstream approaches rely on the use of an excess of strong acids that result in regioselectivities dictated by the innate effect of the protonated heteroarene, leaving the functionalization of other carbons unexplored. We report a mild

4-((1H-benzo[d]imidazol-2-yl)oxy)-3-methylpicolinic acid (11) is a key relatedsubstance of Rabeprazole sodium. In this article, this key relatedsubstance is synthesized by using 3-methylpicolinonitrile as a starting material via a five-step processes. By converting 3-methylpicolinonitrile to 4-hydroxy-3-methylpicolinonitrile (13), the preparation of TM becomes practical. This work provides a guarantee
4-((1 H-苯并[ d ]咪唑-2-基)氧基)-3-甲基吡啶甲酸(11)是雷贝拉唑钠的关键相关物质。在本文中,该关键相关物质是使用3-甲基吡啶啉作为起始原料通过五步法合成的。通过将3-甲基吡啶甲基腈转化为4-羟基-3-甲基吡啶甲基腈(13),TM的制备变得可行。这项工作为建立雷贝拉唑钠的质量标准提供了保证。
